Aeronautical Information Manual
Explanation of Changes

Effective: May

a. 1-2-3. Use of Suitable Area Navigation
(RNAV) Systems on Conventional Procedures
and Routes

This change allows for the use of a suitable RNAV
system as a means to navigate on the final approach
segment of an instrument approach procedure (IAP)
based on a VOR, TACAN, or NDB signal. The
underlying NAVAID must be operational and
monitored for the final segment course alignment.

b. 3-2-3. Class B Airspace

This change adds an RNAV Receiver as an option for
instrument flight rule (IFR) navigation requirement
IAW 91.131 (c)(1).

c. 3-2-5. Class D Airspace

This change clarifies the status of part-time Class D
airspace areas and associated Class E arrival
extensions during periods when a control tower is not
operating. This change closes out Aeronautical
Charting Forum (ACF) recommendation 07-01-195
and is consistent with the revised information
previously incorporated in all volumes of the Chart
Supplement U.S.

d. 3-2-6. Class E Airspace

This change updates the definition, vertical limits,

and types of Class E airspace. The change more

accurately reflects Class E airspace regulatory
information in 14 CFR Part 71 and more clearly states
that Class E arrival extensions have the same
effective times as the airport surface area airspace.
This change also closes out ACF recommendation
07-01-195 and is consistent with the revised
information previously incorporated in all volumes
of the Chart Supplement U.S.

e. 3-5-1. Airport Advisory/Information
4-1-3. Flight Service Stations
4-1-9. Traffic Advisory Practices at
Airports Without Operating Control Towers
Flight Service Stations have discontinued Airport
Advisory services within the Continental U.S.,
Puerto Rico, and Hawaii, due to declining demand
and pilot requests. Therefore, we have removed
references to Remote Airport Advisory service and
Local Airport Advisory service from FAA directives.
Airport Advisory services in Alaska remain
f. 4-1-21. Hazardous Area Reporting Service

This service was reviewed for relevance in the Flight
Service NAS Initiative as was requested so few times
that it was deemed obsolete. Therefore, this change
deletes the Flight Service requirement to publish this

g. 4-2-6. Ground Station Call Signs
4-2-14. Communications for VFR Flights
7-1-1. National Weather Service Aviation
7-1-2. FAA Weather Services
7-1-4. Preflight Briefing
7-1-5. En Route Flight Advisory Service
7-1-6. Inflight Aviation Weather Advisories
7-1-10. Inflight Weather Broadcasts
7-1-11. Flight Information Services (FIS)
7-1-20. Pilot Weather Reports (PIREPS)

7-1-29. Thunderstorm Flying

This change reflects the migration of En Route Flight
Advisory Service responsibilities into the Inflight
position and the discontinued use of the term "Flight
Watch" within the Continental U.S. and Puerto Rico.
The paragraphs within chapter 7 have also been
updated due to changes in Advisory Circular
00-45H, Aviation Weather Services.
